Disconnecting app(Yanosik) from net

[krzygaj]

Hi,
I have a problem with one application - it is called Yanosik and it is a kind of navigation with radar warnings, traffic events, etc. ... During operation, the app quits the screen and if there is any traffic incident, it lights up the screen informing about it.
Unfortunately, after the last reinstallation of the system, something broke down and I have such a symptom that when the application turns off the screen, after 5 minutes Yanosik informs me that there is no connection with the server. If I turn on the screen for a few seconds Yanosik to recovers the connection to the server, but when the screen goes off the situation repeats itself. I also checked and Yanosik behaves the same way when there is a WiFi connection.
When I use Yanosik and the screen is on, there is no lack of communication with the server.
Earlier, Yanosik worked without a problem - unfortunately I do not know what effect the system's upgrade from October had.

Maybe there are some system settings somewhere that make Yanosik lose connection.

Thank you for helping me solve the problem

Did you try to disable the battery optimization for your app?

Settings -> Battery menu -> 3 dot menu -> Battery optimization -> click on Not optimized and choose All apps -> search for your app and click it -> choose Don't optimize.

Other thing might be that background data for the app has been disabled.

Settings -> Apps & Notifications menu -> See all xx (number of apps) apps -> search for your app and click it -> Data usage -> check if Background data is activated
(Maybe even activate Unrestricted data usage aswell.)

I'm afraid beside of uninstalling/reinstalling the app I'm out of ideas. Well, you could downgrade to V9.6.4.0 of the firmware if this app is really important for you.

After a hard fight, Yanosik was able to restore it to its correct operation - the culprit was the AdGuardDNS module installed in Magisk.

Good to hear but strange, I never had any connection losses while using AdGuard DNS on my PC.
